我国地域辽阔,气候差异很大,生态条件极为复杂。如何根据苹果生长发育对生态条件的要求做到适地适栽,对于进一步实现果树的商品化生产具有重要的意义。我们从1980年起用四年时间就我国大苹果栽培北界问题进行了调查研究,东自鸭绿江口起,西至伊犁河谷,历经辽、冀、晋、内蒙古、宁、甘、新等7个省(区),共计调查102个果园。本文即为以国光、金冠和元帅品种为代表的大苹果栽培北界(下文简称北界)的调查总结,以期为探讨我国大苹果适栽北缘提供一些依据。
China has a vast territory, a great climate difference and extremely complex ecological conditions. How to adapt to the requirements of ecological conditions according to the growth and development of apple is very important for the further realization of commercial production of fruit trees. In 1980, we spent four years investigating the cultivation of northern big apple trees in our country. From the mouth of the Yalu River in the east to the Ili Valley in the west, we have gone through seven provinces of Liaoning, Hebei, Shanxi, Inner Mongolia, Ningxia, Gansu and Xinchuang (Districts), a total of 102 orchards surveyed.
